Conceptual design and optimal sizing of a small unmanned aerial vehicle with fuel cell and battery-powered hybrid propulsion system by meta-heuristic algorithms based on energy consumption
(Taylor and Francis, 2023)
In this paper, a new conceptual design methodology for a hybrid propulsion system consisting of the battery and hydrogen fuel cells is presented based on the minimum energy consumption of the UAV. In this context, an ...
Presence of microplastic in the Patella caerulea from the northeastern Mediterranean Sea
(Elsevier, 2023)
This study reports first evidence of microplastic detection in the Patella caerulea collected from 5 different stations located in İskenderun Bay and Mersin Bay. A total of 160 P. caerulea specimens were examined and 40 ...
Synthesis, structural characterization and determination of the nitro-containing explosives detection potential of supramolecular lanthanum complex and Lanthana nanoparticles
(Elsevier, 2023)
A novel nanoparticle sized complex, [La(HO-C6H4-CH2COO)3(H2O)].(H2O), has been prepared by the reaction of LaIII ion and a versatile carboxylate ligand, 4-hydroxyphenylacetatic acid. The obtained complex was structurally ...
Absorbing the entire X-band via conductive polymer polyaniline coated Y3Fe5O12/NiFe2O4 hybrid composites
(Springer, 2023)
Conductive polymer coated Y3Fe5O12 (YIG)/NiFe2O4 (NFO) hybrid radar absorbing composites were studied in this work. The magnetic YIG and NFO particles were synthesized by sol-gel method, and then covered with a conductive ...
Novel Properties of q-Sine-Based and q-Cosine-Based q-Fubini Polynomials
(MDPI, 2023)
The main purpose of this paper is to consider q-sine-based and q-cosine-Based q-Fubini polynomials and is to investigate diverse properties of these polynomials. Furthermore, multifarious correlations including q-analogues ...
Development of a Three-Dimensional CFD Model and OpenCV Code by Comparing with Experimental Data for Spillway Model Studies
(MDPI, 2023)
This article presents a three-dimensional CFD model and OpenCV code by comparing the flow over the spillway with the experimental data for use in spillway studies. A 1/200-scale experimental model of a real dam spillway ...
Artificial intelligence based active and reactive power control method for single-phase grid connected hydrogen fuel cell systems
(Elsevier, 2023)
In grid-connected power generation systems, power factor fluctuations caused by non-linear power circuits used between the grid and source should be controlled with the help of voltage source inverters (VSI). In addition, ...
Investigation of the effect of curing and high temperature on the strength of copolymer added geopolymer mortars
(Taylor and Francis, 2023)
Cracks that occur in geopolymer mortars under the influence of high temperature cause a decrease in strength. In this study, ethylene and methyl-acrylate copolymer-based phase change material added (5%, 10% and 15% by mass) ...
Energetic and Exergetic Performance Investigation of Different Topologies for Hybrid Fuel Cell Vehicles
(Wiley-Hindawi, 2023)
The use of green energy has increased day by day. Environmentally friendly hybrid electric vehicles with low CO2 emissions have gained public attention. However, most battery electric vehicles are still having range problems, ...
A new hybrid meta-heuristic optimization method for predicting UTS for FSW of Al/Cu dissimilar materials
(SAGE Publications, 2023)
Joining of aluminum (Al) and copper (Cu) materials used in aerospace, automotive, chemistry, nuclear, electrical-electronic and energy sector with traditional fusion welding methods has some negative consequences. One of ...
